jtextpane

So I am trying to highlight the keywords in java,which I have stored in a text file, as the user opens a .java file or writes to .java file. I think I know how to tell if the file is of the right type. However, I do not know how to change the color of certain keywords. If anyone could help out that would be great because right now it's pretty confusing. I was wondering if I could use my replace function somehow. I have tried to go about trying to do this with the few methods I have, yet it's still not clear. I have taken out he majority of the methods and listeners, just know they are there

I have the following requirements: I need a scrollable JTextPane. The user may type into this text pane, or text may be inserted into it that is not typed by the user. Think something like an IM window. Although the window must be scrollable to allow the user to review text previously typed, the caret should never move from its position at the end of the text.

Is there a way to get Style , a style name or just even compare whether Style at a certain position of JTextPane with the style I gave the text when inserting? Because for my purpose I created custom JTextPane , StyledDocument and DocumentFilter . So I could choose Style to be used for say regular letters and another Style for numbers. I have also toggle button which while toggled sets DocumentFilter to format numbers differently and while not toggled numbers format regularly so at the end you can't distinguish which numbers have been affected just according to JTextPane's getText() method.
